Re: Error: The System Fan Has Failed!

The BIOS monitors fans using sensors on the motherboard. It could be that the case fan is not turning at the RPM's that it originally did and is giving the message .Or it could simply be a glitch in the sensor, have seen that before.

You could install a monitoring app which reports temps, fan speeds and other info.You can keep an eye on temps to see if they are rising when you get the warning,and also fan speeds.

Running it when no warning is received will give you something to compare with after a warning message.If you see no differences, then you will know it is likely just a sensor error. If on the other hand you see the fan really isn't spinning as fast as normal, it may be time to look into replacing the fan.

Re: Error: The System Fan Has Failed!

Thanks for the post. The error occurs on the first boot-up, so the system is cool, also, I have checked the fans and they appear ok. If the problem is in the BIOS, what corrective action if any can be taken. I have the latest version.

Re: Error: The System Fan Has Failed!

If the problem is only a BIOS error, you could enter BIOS setup and see if you have the option to turn off monitoring fans...some have it/some don't.

It may not actually be a BIOS error but as I mentioned_a faulty sensor on the motherboard giving a wrong reading. It could also be that the fan is taking a bit too long to ramp up to proper PRM's on a cold boot.

I wouldn't change anything without using the monitor I linked to above and first monitoring fan speeds for a while, just to rule out a wearing fan.
